Ascend Casement Windows

Ascend casement window in Pearl White

Flexible hinge left or hinge right design options, and a timeless appeal. Casements offer maximum airflow and superior energy efficiency.

Casement windows create great design flexibility and aesthetic appeal. They are also the perfect choice for acoustic control when paired with the right choice in glass. Don’t lose the big picture or ventilation with the Wideline range of casement windows.

The Ascend casement window adds style, sophistication and controlled ventilation to your home. Includes double perimeter sash seals for inclement weather and improved acoustics. Incorporate fixlites, hilites and transoms for larger window expanses.

Hinged at the side to swing outwards, the Ascend casement window gives a fixed pane look with the benefit of airflow. The Ascend casement window is easy to operate, provides easily controlled ventilation and delivers an elegant solution for large windows. Our versatile sash panels can be manufactured up to a generous 2100mm high and 800mm wide – adding the perfect frame to that stunning view.
